MACHINE FOR DELINTING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 396,996, dated January29, 1889.

Application filed October 14, 1887. Serial No. 252,347. (No model.)

To aZZ whom/it may concern.-

Be it known that I, ERNEST TH. GENNERT, of the city, county, and Stateof- New York, have invented certain new and useful Improvements inMachines for Delinting Cotton-Seed, of which the following isaspecification.

This invention relates to an improved ma chine for removing the shortlint or wool of cottonseed which remains on the same after it has beenpassed through the ginning or linting machine, for the purpose ofpreparing the same in a better manner for extracting the oil containedin the same; and the invention consists of a machine for abradingcotton-seed, which comprises a cylindrical casing or shell composed atthe upper part of segmental slabs of a suitable abrading material, andat a lower part of a metallic shell having short longitudinal slots, andof a rotary brush in the interior of the casing that gives the motion tothe seed. The casing or shell is provided with hoppers at both ends forsupplying the seed and with open ends, so that the abraded seed can passoff at either end of the shell according to the direction of motionimparted to the same by the brush.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved machine for abrading cotton-seed. Fig. 2 is a verticallongitudinal section of the same, part of the brush being broken away;and Fig. 3, a vertical transverse section on line a: :0, Fig.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the casing or shell of myimproved machine for abrading cottonseed after the same has been passedthrough the gin and lintingmachine, the machine having for its objectthe removal of the short lint or fine wool fibers that are left on thecotton-seed after the same has been cleaned in the ginning or lintingmachine. The casing or shell A is formed at the upper two-thirds of itscircumference of arc-shaped stone slabs A, which are provided on theirinterior surfaces with grooves or furrows having slight spiral pitch,said slabs being supported by segmental standards B and retained bycircumferential bands B, attached to said standards by screwbolts 1), asshown clearly in Figs. 1 and 3. The lower third or bottom of the casingor shell A is formed ofa metallic plate or section, A of suitablethickness, which is provided with short longitudinal slots (.1, that arepunched into the metallic plate. The slotted bottom part rests on thestandards B, as shown in Fig. 3. The casing or shell A is open at bothends, and provided at both ends with hoppers C for supplying thecotton-seed. A rotary brush, D, is arranged in the shell, the brushbeing made of cylindrical shape and supported on spider-frames D, thatare keyed to a longitudinal center shaft, D which is supported in.hearings in the end standards, E, that arearranged at a short distancefrom the ends of the shell or casing A, so as to leave a space ofsufficient width for dropping the abraded cotton-seed from the edge ofthe shell. According to the direction in which the cylii'uler-brush isturned, the seed is passed either in one or the opposite directionthrough the shell A, the direction of motion of the brush being reversedfrom time to time for the purpose of uniformly wearing off the abradingsurfaces of the slabs A. The short fibers that are removed from thecotton-seed by the abrading action of the furrowed slabs are droppedthrough the slots of the bottom section of the shell by the action ofthe brush, while the cleaned seed is delivered at either end, as shownby the arrows in Fig. *3. The seed is delivered to separate receptaclesat the ends of the machine, while the short fibers are collected inreceptacles below the shell. The width of the grooves or furrows of theabrading slabs corresponds in width and depth to the general shape ofthe cotton-seed, the fibers on the same being abraded by the action ofthe roughened surfaces of the slabs, which may be made of any suitableabradingmaterial.

When the cotton-seed is cleaned by removing the wool fibers, it is in acondition for being broken or cracked by the crushing-mill, so that theoil can be extracted in a more perfect manner from the seed, as theremoval of the fibers facilitates the crushing and pre paring of theseed for the production of cotton-seed oil.

I am aware that abrading-machines for cotton-seeds have been usedheretofore, in which a fixed exterior cylinder is used which is providedwith abradingmaterial at its inner surface, said cylinder beingperforated for the discharge of the lint removed from the seeds.

\Vithin the exterior cylinder is arranged a rotary interior cylinderhaving a rasp or grating-surface, which, in connection with theabrading-surface of the exterior cylinder, removes the lint from theseeds. In my machine the aln-ading'surface is confined to the upper partoi? the exterior cylinder, while the lower part has no abrading-surface,but is provided with slots for the discharge of the lint dropping fromthe seeds. This is a more effective arrangementthan that heretofore inuse.

llavii'ig thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with a rotary cylindricalbrush, ot' a fixed exterior easing or shell extending around said brush,and composed of an upper part provided with an abrading material havinggrooves or furrows and of a smooth and slot-ted bottom part,substantially as set forth.

2. The combination of an exterior casing or shell, the upper surface ofwhich is provided with abradin g material having grooves or furrows,said casing having a slotted bottom part and being provided with openends, with an interior cylindrical brush, substantially as set forth,

The combination of an exterior shell or casing, the upper surface ofwhich is formed of a series of slabs of abrading material, said casingor shell having a slotted bottom part,

and said slabs having spirally-arranged grooves or furrows, with aninterior rotary brush central to the casing and standards for supportingthe shaft of the brush, substantially as set forth.

4. The combination of an exterior casing or shell formed at the upperpart of abrading material and having grooves or furrows, said shell orcasing having a slotted bottom part, supporting-staridards, andencircling-bands for said casing, with an interior rotary brushsupported centrally to the casing, said casing being open at the endsand provided with supply-hoppers at both ends, substantially as setforth.

In testimony that I claim the foregoing as myinvention I have signed myname in presenee of two subscribing witnesses.
